No DTC. fass shows 18psi. All new cables last year. Batteries are good, i tested them about a month ago at work. Even putting the stock file back into the truck, it'll still do it.
I've had the truck for about 4-5 years now. Because I live in the salt belt, I did a cab swap about 3 years back. Dual stock cp3s, 209% injectors, rebuilt 6.7 with Brian Crower Rods, 625 studs, fire ringed fleece stage 3 head, 10 bar map sensor, 6.7 rail sensor, s467.6 over a psr 92. Trans has a solid input shaft with a 2600 stall converter, extreme intermediate shaft (the one where you gotta machine the overdrive planetaries), fat output shaft, muldooms fmvb, other basic billet parts. All the suspension has been replaced. Whole new ac system and steering system. Almost everything on the truck has been replaced within the last 4-5 years, except for any of the wiring in the truck. Dash shows a little over 248k miles.
